Biosensing by Cantilever Resonator for Disease Causing Pathogen Detection

P. Sangeetha, Dr. A. Vimala Juliet

Abstract :

Microcantilever biosensors can detect small amounts of materials such as pathogenic bacteria for medical diagnostics. These biosensors can be used as immunobiological detectors for a specific disease. This paper gives a resonant frequency based biosensor using cantilever beam for detection of tuberculosis based on antigen antibody binding events. This binding event is due to the interaction of antibody immobilized on the surface of the cantilever and the antigen 85 complex in the blood sample. Increase in mass due to antigen antibody specific binding can be detected by  measuring a resonant frequency shift. Simulation of the resonator was done using HFSS software and the analysis of the cantilever was performed using Matlab.
